"These sneakers are my favorite of about 10 pair I own. I am going to get the navy ones as well. I'm usually around an 8, I ordered up to 8 1/2 and they fit perfect. I will say the purple is a bit brighter than it shows (on my screen, anyway), not so much a deep purple, but a bit more plumish. Love them now, was a little troubled when I first got them. I did spray them with waterproofing spray, and that toned them down to a happy place. Also, if you go to a store and have them place the order, you don't pay $7 shipping."
